1045 is a medium tensile low hardenability carbon steel
1045 Carbon Steel , S45C, 1191, ASSAB 760, EN9, C45, 45C
Typical applications are: Axles Various, Bolts, Connecting Rods, Hydraulic Clamps and Rams, Pins Various, Rolls Various, Studs, Shafts, Spindles etc.
|Flame or Induction Hardening|
|Heat as quickly as possible to the austenitic temperature range (820 oC – 860 oC) and required case depth followed by an immediate water or oil quench, depending upon hardness required, workpiece size/shape and quenching arrangements.
Following quenching to hand warm, most components should be tempered at 150 oC – 200 oC to remove quenching stresses in the case. This will have little effect on case hardness.
